Use this symbiosis project to reinforce symbiotic relationships in ecosystems (mutualism, commensalism, and parasitism) by creating a mobile to present the information. Teacher can use presentation to introduce concepts of symbiosis, mutualism, commensalism, and parasitism in the ecosystem and then reinforce with the mobile project. Students watch videos and discuss ecological relationships with a focus on observing symbiosis. Then they classify the ecological relationships they observe as mutualism, commensalism, and parasitism. Explain to students that they will watch footage from a National Geographic project called.
A big thanks to all current and future patrons who are helping fund this science communication outreach via Patreon:Symbiosis is close and often long-term interaction between different biological species.The definition of symbiosis is controversial among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to all types of persistent biological interactions (i.e. Mutualistic, commensalistic, or parasitic).In this video we show how you can simply visualize all three.For more info on this topic visit our page:Don't forget to subscribe to this channel for more great science videos!Our GEAR -Main DSLR:Second Camera:Main Lens -The Adventure Camera Bag:The Macro Lens -Telephoto Lens -Our Mega Wide Lens -Our BEST On-camera Mic -The Drone -My Moving Timelapse setup -GoPro HERO 7 -Our Filmmaking Book!!! -Our Music:The full video setup:(By buying through these links you help us support the channel)On Social -Instagram: (Jonas @behindthescience)Twitter:Facebook:Website:Youtube: (for most of my work)Jonas and I are creating a whole series of how-to-filmmaking videos to get you started.

When two species have a mutually beneficial symbiotic relationship, we call it 'mutualism.' This type of symbiosis benefits both partners. To understand mutualism better, let's examine the interaction between clown fish and anemones. Most fish stay away from an anemone for fear of touching its poisonous tentacles. But clown fish have a special coating on their skin that protects them from getting stung. (This trick does not work for all anemones though. Clown fish can only have symbiotic relationships with 10 of the 1,000 different anemone species in the world.) Clownfish can swim carefree and unharmed among their host's deadly tentacles.
They know very well that their predators do not dare to come near them. Plus, clown fish get to eat the leftover bits of food discarded by their landlord. What does the anemone get in return for offering clown fish a safe haven? Well, it kills and feeds on fish that are eyeing its tenant! Aside from that, clown fish pay their rent by cleaning up food scraps and dead anemone tentacles. The second type of symbiosis is called 'commensalism.'
In this type of symbiotic relationship, only one party emerges as the clear winner. As for the other party involved, it neither benefits nor suffers from the partnership. Let's look at the case of remoras and sharks.
Remoras have sucking disks above their heads that they use to attach themselves to large marine animals, especially sharks. Hence, remoras are also known as 'shark suckers' or 'sucker fish.' Remoras are the clear winners in this relationship. First, they save energy by delegating the task of swimming to their host.
Second, they do not have to worry about predators whose exact nightmare is to run into hungry sharks. Third, they feed on the food scraps of their host's latest victim or the parasites from their host's skin. What do sharks get out of this partnership? Well, nothing really. Except for remoras' parasite-cleaning work that they can live without, sharks gain nothing and lose nothing by having remoras around. 5 'Parasitism' is the third and last type of symbiosis. In this relationship, one (the parasite) wins and the other (the host) loses.
There are many examples of parasitism around us. For instance, leeches also have sucking disks. When a leech finds an ideal host, say a little boy named Frank, it fastens itself firmly onto his skin and starts sucking blood. Amazingly, it can consume about 3 times its weight in blood in one feeding! Frank not only loses his blood but also runs a risk of getting infected by the viruses that the leech may carry.
While all parasites do harm to their hosts, some extremists go as far as killing their hosts!
